Unlocking the SIM Card
When your SIM has been locked, you will need to enter the PUK code to unlock your SIM card.
Use the sim_unlock –p PUK code –n new PIN code command to unluck your card. Please note
that when you enter the PUK code, you also need to provide a new PIN code. For example, type
sim_unlock –p 80364944 –n 0000. In this case, 80364944 is the PUK code, while 0000 is the new
PIN code. Use this new PIN code the next time the W406 starts.
